Need to find the distance for this problem. I found acceleration and tension.Can someone work this out step by step.

two objects with masses of 9.76kg and 4.81kg hang 2m from the floor from the ends of a cord 8.0m long passing over a frictionless pulley. Both objects are released from rest. What is the maximum height above the floor reached by the 4.81kg object.

nvm i get it since i think 4.81 is less than half the mass of the original it won't have an affect right?

I hope it is not that easy
I thought when the heavier object traveled down 2m that the light object would go up 2m+2m and then it would travel a little more to de-accelerate.
